    • A method, storage medium, and system for selecting an optimal trigger point in a cardiac cycle includes providing an input signal including non-electrical cardiac related data, analyzing the input signal to detect candidate features, sorting through the candidate features to select optimal features, and selecting an optimal trigger point. A method, storage medium, and system of selecting an arbitrary cardiac phase for cardiac gating includes identifying a trigger point identifying onset of a systole or diastole phase on a signal, the trigger point existing at time t1, specifying a time &dgr; t before the trigger point and extending from a time t0 to a time t1, wherein time t0 is earlier than time t1, and selecting a time interval T over which an image will be reconstructed, wherein the time interval T extends from time t0 to a time t2, wherein time t2 is later than time t0.
    • 一种用于在心动周期中选择最佳触发点的方法,存储介质和系统包括提供包括非电心脏相关数据的输入信号,分析输入信号以检测候选特征,通过候选特征排序以选择最佳特征, 并选择最佳触发点。 选择用于心脏门控的任意心脏期的方法,存储介质和系统包括识别识别信号上的收缩期或舒张期开始的触发点,触发点在时间t1存在触发点,指定在触发之前的时间增量t 并且从时间t0延伸到时间t1,其中时间t0早于时间t1,并且选择将重构图像的时间间隔T,其中时间间隔T从时间t0延伸到时间t2,其中 时间t2比时间t0晚。
